The problem is a 1970's floor standing Potterton C50/15/SB.
I know.... why bother repairing it. The people that own it are far older and want
to keep it going to see them out.
It has been extremely reliable only requiring a replacement circulation pump and
several Thermo couple sensors over the years.
Problem now is the boiler will not light up. Main gas solenoid has gone open circuit. I believe
the resistance should be in the region of 5.2K Ohms.
The part number on the gas valve is V404A 1006 1 LW. 240V 0.02amp.
I contacted The Plumb Centre Parts depot and they have part number V404A (Solenoid)
Would this part be interchangeable with V404A 1006 1 LW 240V .02amp ?[/img]
